Thank you Scott!
On the last picture one can see something, that I was bothering about since some time.
The monogram appears sitting quite thickly on the barrel. I already used the thinnest material available from my supplier, 0,2 mm equals 2 cm in original. The original monogram is about 5 to 10 mm mm but has much more washed outlines.
Time to tinker a bit and to see what still is possible
Two versions were spooking around my wired minds for some time - lets go for the phantoms
Version
1 sinking the monograms with a soldering iron.
Worked surprisingly well, it was quite easy to sink it evenly ...
... until I saw the bulges of diplaced material all around. Difficult to take out, ok forget it.
Version
2 were thin castings, like those I do successfully for the coat of arms of the entry port.
Took two monograms and hammered them into the poly ...
... casted twice ...
... but missing a good form success was not coming. Some carvings of the form did not help.
Then came version
3, gluing the monograms and filing the edges off.
Looked great without color but with color splashed over ...
... merda ...
...
Ok trial number 4:
Took a monogram and sank it by half into a poly ...
... broke it out ...
... and took the poly as holder to file down the backsides of the monograms down to half ...
... and bingo
Some other side theaters of war ...
... rolled the wire for the thread rod with the filr to give it some structure ...
... and carved the bearings of the trunnion out of Evergreen.
On the last picture one can see that the sliding part has to slide over the mounts of the wheels, so it means, they have to be flush in the surface.
So marked the position on the circle ...
... and used a dummy for testing. First drilled a basic hole ...
... ground a old scalpel into shape ...
... and formed the drilled hole.
And the trials shows that it fits
So assembled the carriage and barrel, splashed some paint onto it, fitted the appropriate eyebolts and it looks ok
Old and new side by side ...
... old - once state of the art - ...
... and a bit pimped ...
... and it seems quite ok
